Description

Technical Field

[0001] This utility model belongs to the field of thin paper coating technology, specifically relating to a thin paper coating adsorption and feeding mechanism. Background Technology

[0002] In the modern printing and packaging industry, tissue lamination is a common process used to increase the strength, water resistance, and durability of tissue paper. To improve production efficiency and reduce labor costs, automated tissue feeding technology has been widely adopted. Traditional tissue feeding methods often rely on manual operation, which is inefficient and prone to errors, especially when handling tissue paper of different sizes and specifications, where the accuracy and repeatability of manual feeding are difficult to guarantee.

[0003] Currently, existing tissue paper laminating and loading technologies mainly involve using robotic arms or simple clamps to handle the tissue paper. These technologies typically include a fixed loading platform, which may have simple limiting devices to fix the position of the tissue paper. The handling process may involve pneumatic or electric robotic arms, which are responsible for gripping the tissue paper and placing it on the laminating machine. However, existing loading technologies are difficult to adapt to tissue paper of different sizes and specifications, requiring manual adjustment or clamp replacement, resulting in reduced production efficiency. Robotic arms or clamps may not be able to precisely control the position of the tissue paper during loading, affecting the lamination quality. Using robotic arms to grip the tissue paper may cause physical damage, especially to fragile materials.

[0004] In view of this, we propose a thin paper adhesive adsorption feeding mechanism. By adopting an adjustable limiting mechanism and a servo-driven conveying component, it can better adapt to thin paper of different sizes, improve feeding accuracy and efficiency, reduce damage to the thin paper, and improve the overall reliability and automation level of production. Utility Model Content

[0005] The present invention aims to solve the technical problem in the prior art where the use of robotic arms to grip thin paper during the lamination of thin paper may cause physical damage to the thin paper and is difficult to adapt to thin paper of different sizes and specifications, requiring manual adjustment or replacement of the clamps.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A paper lamination and adsorption feeding mechanism includes a feeding platform and a feeding assembly. The feeding platform is used to place stacks of paper to be fed, and the feeding platform is provided with a limiting mechanism for limiting the paper of different sizes. The feeding assembly is used to feed the paper on the feeding platform to the lamination station.

[0008] The feeding assembly includes a vacuum suction cup for adsorbing thin paper, a vertical servo screw linear module for driving the suction cup to rise and fall, and a flat-push cylinder for pushing the vertical servo screw linear module and the vacuum suction cup to move back and forth.

[0009] The action of the horizontal push cylinder drives the vacuum suction cup and the vertical servo screw linear module to move backward to above the thin paper. The action of the vertical servo screw linear module drives the vacuum suction cup to move down to pick up the thin paper on the feeding station. The action of the vertical servo screw linear module drives the vacuum suction cup to move up. The action of the horizontal push cylinder drives the vacuum suction cup and the vertical servo screw linear module to move forward to feed the thin paper to the gluing station.

[0010] As a preferred embodiment, the limiting mechanism includes four sets of limiting vertical plates that limit the left and right sides of the stack of thin paper, and a limiting horizontal plate that limits the rear side of the stack of thin paper.

[0011] The four sets of limiting vertical plates and limiting horizontal plates can effectively fix the left, right and rear sides of the stacked thin paper, preventing the thin paper from moving or tilting during the feeding process, and ensuring that the thin paper can be accurately adsorbed and transported.

[0012] As a preferred embodiment, the feeding platform is provided with two horizontally arranged straight slots, the limiting plate is fixed on the rectangular limiting block, and the rectangular limiting block is threaded with a threaded locking rod A that passes through the straight slot A. The bottom of the threaded locking rod A is fixedly connected to the straight block A located below the feeding platform.

[0013] The rectangular limit block is locked and fixed to the loading platform or removed from the loading platform by rotating the threaded locking rod A and engaging with the straight block A. The rectangular limit block's position can be easily and quickly changed and adjusted through the engagement of the threaded locking rod A and the straight block A.

[0014] Preferably, two sliding blocks are fixedly connected to both ends of the limiting plate. The sliding blocks cooperate with two longitudinal guide rails on both sides of the feeding platform for guidance and sliding. The sliding blocks are locked and fixed to the longitudinal guide rails by locking bolts. The locking bolts can quickly fix the position of the sliding blocks on the longitudinal guide rails to adapt to the limiting requirements of thin paper of different widths.

[0015] Preferably, a lifting seat is fixedly provided on the lifting slide of the vertical servo screw linear module, and a lifting platform is fixedly provided at the bottom of the lifting seat. Several straight slots B are arranged at equal intervals on the lifting platform. A vacuum suction cup is fixed on the C-shaped support block. A threaded locking rod B is threaded through the C-shaped support block and passes through the straight slot B. The bottom of the threaded locking rod B is fixedly connected to a straight block B located inside the C-shaped support block.

[0016] The U-shaped support block is locked and fixed to the lifting platform or removed from the lifting platform by rotating the threaded locking rod B and engaging with the straight block B. The U-shaped support block can be quickly installed or removed using the threaded locking rod B. The engagement of the threaded locking rod B and the straight block B allows for precise adjustment of the vacuum suction cup's position, ensuring accurate adsorption of thin paper at different locations.

[0017] Preferably, the fixed end of the horizontal push cylinder is fixed to an inverted U-shaped bracket on the top of the loading platform. The piston rod end of the horizontal push cylinder is fixedly connected to the vertical servo screw linear module. The inverted U-shaped bracket is also equipped with a guide frame. The vertical servo screw linear module is guided and slid through the cooperation of the guide block and the guide frame. The cooperation between the horizontal guide frame and the guide block provides additional guiding support, ensuring the linearity and repeatability of the vertical servo screw linear module during its forward and backward movements.

[0018] Preferably, the inverted U-shaped support is equipped with a tracheal support, and the vacuum tube on the tracheal support passes through the tube hole on the C-shaped support block and connects to the vacuum suction cup.

[0019] Compared with the prior art, the technical effects and advantages of this utility model are:

[0020] This thin paper lamination and suction feeding mechanism precisely fixes the thin paper through a limiting mechanism, and utilizes the coordinated action of a servo screw and a cylinder. The limiting mechanism uses adjustable vertical and horizontal plates to fix thin paper of different sizes, preventing it from shifting or tilting during handling. The combination of a vertical servo screw linear module and a vacuum suction cup enables precise adsorption and handling of the thin paper. Through the coordinated control of the electrical control system, the entire feeding process is efficient, precise, and stable.

[0021] This thin paper lamination and adsorption feeding mechanism can automatically complete the adsorption, handling and placement of thin paper, greatly reducing manual operation and improving production efficiency. The flexibility of the limiting mechanism allows the equipment to adapt to different specifications of thin paper, increasing the applicability and flexibility of the equipment. In addition, the combination of vertical servo screw linear module and vacuum suction cup ensures the accuracy of thin paper at the lamination station, thereby improving the lamination quality.

[0022] This thin paper laminating and feeding mechanism utilizes vacuum suction cups to adsorb thin paper, reducing physical damage compared to traditional robotic gripper methods, making it particularly suitable for fragile thin paper materials. Simultaneously, precise control via servo screws and cylinders minimizes potential instability during operation, enhancing safety and reliability. These advantages collectively make this thin paper laminating and feeding mechanism a highly efficient, safe, and reliable automated solution. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] The following combination Figures 1 to 5 This application will be described in further detail;

[0031] This application discloses a paper adhesive adsorption feeding mechanism, including a feeding platform 1 and a feeding component 4. The feeding platform 1 is used to place stacks of paper 2 to be fed, and the feeding platform 1 is provided with a limiting mechanism 3 for limiting the paper 2 of different sizes.

[0032] The limiting mechanism 3 includes four sets of limiting vertical plates 31 that limit the left and right sides of the stacked thin paper 2, and a limiting horizontal plate 32 that limits the rear side of the stacked thin paper 2. The four sets of limiting vertical plates 31 and limiting horizontal plates 32 can effectively fix the left, right and rear sides of the stacked thin paper 2, preventing the thin paper 2 from moving or tilting during the feeding process, and ensuring that the thin paper 2 can be accurately adsorbed and transported. By adjusting the position of the limiting vertical plates 31 and the horizontal plates, it can quickly adapt to thin paper 2 of different sizes, increasing the flexibility of the equipment.

[0033] The loading platform 1 is provided with two horizontally arranged straight slots. The limiting plate 31 is fixed on the rectangular limiting block 33. The rectangular limiting block 33 has a threaded locking rod A34 that passes through the straight slot A101. The bottom of the threaded locking rod A34 is fixedly connected to the straight block A35 located below the loading platform 1.

[0034] The rectangular limiting block 33 is locked and fixed on the loading platform 1 or removed from the loading platform 1 by rotating the threaded locking rod A34 and the straight block A35.

[0035] The rectangular limiting block 33, through the cooperation of the threaded locking rod A34 and the straight block A35, can be quickly fixed to the feeding platform 1 or quickly disassembled, facilitating rapid replacement and adjustment of the position of the rectangular limiting block 33. The fixing method of the threaded locking rod A34 increases the stability of the rectangular limiting block 33, ensuring that the position of the thin paper 2 will not change due to the movement of the rectangular limiting block 33 during the feeding process. The design of the straight groove A101 allows the rectangular limiting block 33 to move quickly in the horizontal direction, reducing the time required to adjust the position of the rectangular limiting block 33.

[0036] Two sliding blocks 36 are fixedly connected to both ends of the limiting horizontal plate 32. The sliding blocks 36 cooperate with the two longitudinal guide rails 102 on both sides of the feeding platform 1 for guidance and sliding. The sliding blocks 36 are locked and fixed to the longitudinal guide rails 102 by locking bolts 37. The cooperation between the sliding blocks 36 and the longitudinal guide rails 102 provides stable and precise guidance, so that the limiting horizontal plate 32 will not shift during adjustment, ensuring the correct placement of the thin paper 2. The locking bolts 37 can quickly fix the position of the sliding blocks 36 on the longitudinal guide rails 102 to adapt to the limiting requirements of thin paper 2 of different widths. The design of the sliding blocks 36 makes the adjustment process of the limiting horizontal plate 32 simple and quick, which helps to improve production efficiency.

[0037] The feeding assembly 4 is used to feed the thin paper 2 from the feeding platform 1 to the gluing station;

[0038] The feeding assembly 4 includes a vacuum suction cup 41 for adsorbing the thin paper 2, a vertical servo screw linear module 42 for driving the suction cup to rise and fall, and a flat cylinder 43 for pushing the vertical servo screw linear module 42 and the vacuum suction cup 41 to move back and forth.

[0039] A lifting seat 45 is fixedly provided on the lifting slide 44 of the vertical servo ball screw linear module 42. A lifting platform 46 is fixedly provided at the bottom of the lifting seat 45. Several straight slots B47 are arranged at equal intervals on the lifting platform 46. A vacuum suction cup 41 is fixed on the U-shaped support block 48. A threaded locking rod B49 is threaded through the U-shaped support block 48 and passes through the straight slots B47. The bottom of the threaded locking rod B49 is fixedly connected to the straight block B410 located inside the U-shaped support block 48.

[0040] The C-shaped support block 48 is locked onto or removed from the lifting platform 46 by rotating the threaded locking rod B49 in conjunction with the straight block B410.

[0041] The straight slot B47 on the lifting platform 46 allows the vacuum suction cup 41 to be fixed on the U-shaped support block 48, which can be quickly installed or removed via the threaded locking rod B49. This modular design makes maintenance and component replacement more convenient. The position of the vacuum suction cup 41 can be precisely adjusted by the cooperation of the threaded locking rod B49 and the straight block B410, ensuring accurate adsorption of the thin paper 2 at different locations.

[0042] The fixed end of the horizontal push cylinder 43 is fixed to the inverted U-shaped bracket 411 on the top of the loading platform 1. The piston rod end of the horizontal push cylinder 43 is fixedly connected to the vertical servo screw linear module 42. The inverted U-shaped bracket 411 is also equipped with a guide frame 412. The vertical servo screw linear module 42 is guided and slid through the guide block 413 in cooperation with the guide frame 412. The direct fixed connection between the horizontal push cylinder 43 and the vertical servo screw linear module 42 makes the forward and backward movement and lifting movement more coordinated, improving the smoothness and accuracy of the handling process. The cooperation between the guide frame 412 and the guide block 413 provides additional guiding support, ensuring the linearity and repeatability of the vertical servo screw linear module 42 in forward and backward movement.

[0043] The inverted U-shaped bracket 411 is equipped with an air tube support 414. A vacuum tube 415 on the air tube support 414 passes through a tube hole 416 on the U-shaped support block 48 and connects to the vacuum suction cup 41. The design of the air tube support 414 makes the connection of the vacuum tube 415 more convenient, and also facilitates daily maintenance and repair. By ensuring a reliable connection between the vacuum tube 415 and the vacuum suction cup 41, suction cup failure due to connection problems during transportation is avoided. The positional design of the air tube support 414 avoids interference between the air tube and other moving parts, improving the reliability of equipment operation.

[0044] The action of the horizontal push cylinder 43 drives the vacuum suction cup 41 and the vertical servo screw linear module 42 to move backward to above the thin paper 2. The action of the vertical servo screw linear module 42 drives the vacuum suction cup 41 to move down to pick up the thin paper 2 on the feeding station. The action of the vertical servo screw linear module 42 drives the vacuum suction cup 41 to move up. The action of the horizontal push cylinder 43 drives the vacuum suction cup 41 and the vertical servo screw linear module 42 to move forward to feed the thin paper 2 to the gluing station.

[0045] The limiting mechanism 3 positions the thin paper 2 placed on the platform to ensure that the thin paper 2 does not shift or tilt during the loading and handling process. For thin paper 2 of different sizes, the limiting mechanism 3 can be adjusted in position and size to ensure that the thin paper 2 is in the correct position before gluing.

[0046] The vacuum suction cup 41 uses the negative pressure created inside to adhere the thin paper 2. When the vacuum pump works, the air inside the suction cup is extracted, creating a pressure lower than the external atmospheric pressure, causing the thin paper 2 to be adhered to the surface of the suction cup. The vertical servo lead screw linear module 42 drives the lead screw to rotate via a servo motor. The rotation of the lead screw is converted into linear motion, which drives the connected vacuum suction cup 41 to move vertically. The principle of the horizontal push cylinder 43: The horizontal push cylinder 43 is a device that converts the energy of compressed air into linear motion energy. When compressed air enters one end of the cylinder, it pushes the piston inside the cylinder to move, thereby driving the connected load (in this example, the vacuum suction cup 41 and the vertical servo lead screw linear module 42) to move horizontally.

[0047] The limiting mechanism 3 secures the thin paper 2, ensuring its correct placement on the loading platform 1. The horizontal push cylinder 43 moves the vacuum suction cup 41 and the vertical servo screw linear module 42 above the thin paper 2. Then, the vertical servo screw linear module 42 descends, causing the vacuum suction cup 41 to contact and adhere to the thin paper 2. The vertical servo screw linear module 42 rises, separating the suction cup from the thin paper 2. Then, the horizontal push cylinder 43 pushes the suction cup and module horizontally, transporting the thin paper 2 to the gluing station. Upon reaching the gluing station, the vertical servo screw linear module 42 descends, placing the thin paper 2 on the gluing machine. Then, the vertical servo screw linear module 42 rises, and finally, the horizontal push cylinder 43 retracts the suction cup and module to their starting positions.

[0048] The entire process is controlled by an electrical control system to ensure the coordination and accuracy of each action. The design principle of this feeding mechanism enables an efficient, precise, and stable feeding process for thin paper.

[0049] This thin paper lamination and adsorption feeding mechanism can automatically complete the adsorption, handling, and placement of thin paper 2, greatly reducing manual operation and improving production efficiency. By using limiting mechanisms 3 for different sizes of thin paper 2, it can accommodate different specifications of thin paper 2, increasing the flexibility and applicability of the equipment. The combination of the vertical servo screw linear module 42 and the vacuum suction cup 41 can precisely control the position and movement of the thin paper 2, ensuring the accuracy of the thin paper 2 at the lamination station and improving lamination quality. Using the vacuum suction cup 41 to adsorb the thin paper 2, compared to robotic gripping, reduces physical damage to the thin paper 2, especially for fragile materials. Precise control through the servo screw and cylinder reduces potential instability factors during operation, improving operational safety.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
